Workaroud is to kill -9 grub-mount.
The exact report is it depends on the hf+ filesystem. Somtimes, the hfs 
driver goes into an infinite loop while reading the metadata.

The exact condition under which this problem happens is unknow.

Title:
  grub-mount hangs when update-grub is ran

Status in “grub2” package in Ubuntu:
  Triaged

Bug description:
  Whenever my system tries to build the grub.cfg, the grub-mount hangs and I have to kill it 3 times before the command completes.
  I had a look on the internet and I got this links which is related :

  http://lists.gnu.org/archive/html/grub-devel/2012-02/msg00206.html

  To sum up, I have a 3 fs on my disks which are hfs+ and grub-mount
  hangs each time it tries to process them.

  Problem seems to have been fixed upstream.
